Subject: kernel: add kmod-iio-bmp280
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=683350873e18f592124cb2cce771d5459d27b2bd;p=openwrt%2Fstaging%2Fnbd.git

kernel: add kmod-iio-bmp280

This driver supports the Bosch Sensortec BMP180/BMP280 pressure and
temperature sensors. It also supports the BME280 sensors with an
additional humidity channel.

Tested I2C and SPI modes with a BME280 sensor on a Raspberry Pi Zero W.
